JPSO Col. John Fortunato confirmed the incident happened Friday evening in the Lakeside Mall parking lot after a parade in Metairie.

The YouTube video begins with 17-year-old Brady Becker being held down on the ground by a man who has his hand around the teen's throat. Moments later, the situation escalates when the man begins punching Becker in the face.

Becker was taken to a hospital and treated for his injuries. The JPSO booked the teen on complaints of possession of alcohol by a minor, resisting arrest, battery on a police officer and inciting a riot after his release.

Fortunato said the altercation ensued after an apparent encounter with Becker and his friends as they were returning to their car in the parking garage. He said the undercover deputy was one of many who were working parade routes that evening.

WDSU contacted Becker's mother, who said the teen did not know the undercover officer was with the JPSO and was sticking up for his friend. He admits to pushing one of the deputies because he was not aware of their position.

The circumstances leading up to the altercation remain unclear.

Fortunato said the JPSO learned of the YouTube video and reached out to the family. He said the JPSO is cooperating and open to investigating, but the family is required to file a complaint with the Internal Affairs division.

He said the family hasn't made further contact with the JPSO. WDSU received no additional comments from the mother or the family's attorney.
